Abstract

The invention discloses a method for producing a lampblack-free gas hood lining of a smoke exhaust ventilator. The method comprises the following steps of: (1) uniformly stirring white cement, black cement, mountain flour and gypsum powder in a mass ratio of 3:3:1:1 to form lining powder, and adding glue to ensure that the mixture is muddy so as to prepare gas hood lining mud; (2) coating the lining mud in a gas hood module, wherein the thickness is 0.1 to 0.3 centimeter, covering a layer of gauze or steel wire gauze, coating the lining mud on the gauze, wherein the thickness is 0.1 to 0.3 centimeter, covering a layer of gauze or steel wire gauze, coating the lining mud on the gauze, wherein the thickness is 0.1 to 0.3 centimeter, and hardening and demoulding to prepare a gas hood lining blank; and (3) polishing the inner wall of the gas hood lining blank, and spraying the gas hood lining mud on the inner wall of the gas hood lining to ensure that the surface is smooth so as to obtain the lampblack-free gas hood lining. Lampblack is not adhered to the lampblack-free gas hood lining so as to ensure a clean and tidy environment.

Description

technical field [0001] The utility model relates to a production method for an inner lining of a fume-free fume hood. Background technique [0002] Range hoods are widely used in people's lives. The hood is an important part of the range hood. After the commonly used range hood lining is used for a period of time, a thick layer of grease will form on the surface, which pollutes the environment and is not beautiful. In order to solve the above problems, people have done a lot of research and development, and produced various fume-free hood linings, but most of the fume-free linings only weaken the generation of grease, and the effect is still unsatisfactory. There are also some fume-free hood linings, although the effect is better, but the cost is high, making it difficult for ordinary consumers to accept. Contents of the invention [0003] The object of the present invention is to solve the problem that the inner lining of the hood of the range hood is prone to oil stai...
